Description

The S203-C6 miniature circuit breaker from ABB’s System pro M compact S200 range provides efficient protection for three-phase circuits across residential, commercial, and industrial installations. Featuring a dual tripping mechanism—a delayed thermal trip for overloads and an electromechanical trip for short-circuits—it guarantees accurate fault detection and interruption. With a Type C tripping characteristic, it is ideal for circuits with moderate inrush currents such as lighting systems, HVAC equipment, and control circuits. The 3-pole modular design ensures complete phase isolation and simple DIN-rail mounting. Optional bottom-fitting auxiliary contacts can save up to 50% of enclosure space. For fully integrated electrical systems, the S203-C6 fits perfectly within our industrial panel fabrication solutions.
